"My Way" killings in the Philippines --- a bit funny

I saw this article in Wikipedia, and I could not help but laugh.

I am already familiar with these kinds of incidents here in the Philippines, so it is not a shock for me. What made me laugh though is that there is an article on this, which means these kind of killings are common. It is also a bit disturbing for me as people end up in violence or being killed instead of enjoying the singing.
What about in your country? Does this happen too? For Filipinos (and non-Filipinos as well), what can you say about this?
